摘要
作为动力学与控制学科的一个分支,车辆动力学与控制方向的研究近年来一直很受重视。轮轨式轨道车辆在基础研究、技术攻关和产品研发等领域不断取得重要进展,这得益于近20年来我国轨道交通领域的快速发展和国家科技部门的大力支持。本文从我国轮轨式轨道车辆的发展趋势、特点和运营过程中遇到的主要问题等研究角度出发,重点介绍了轨道车辆的载荷分析与减振降噪方法,轨道车辆动力学建模、计算方法和新型结构的动态设计,以及轨道车辆关键旋转部件的状态识别等三个方面的研究成果。这些成果在一定程度上反映了作者们目前所关注的问题和拟解决途径,希望能给轨道车辆动力学与控制领域的其他研究者们提供一些借鉴和参考。
As one of part of dynamics and control research field,the development of vehicle system dynamics and control has attracted more and more attentions in recent twenty years.Getting benefits from railway traffic quickly development and huge found from government of China,railway vehicle filed has achieved many important progresses continuously in fundamental research,technology research,product development and so on.Starting from development trend,characteristics and the main problems in operating of railway vehicle in China,this paper focus on the research achievements in load analysis,vibration and noise reducing,modeling and simulation,new structure designing,health state identification of the key rotating parts and so on.These research content represents the key problems and study methods of authors in some degree,and may be useful to other researchers in railway vehicle system dynamics and control filed.
